What does the Corneal Cross-Linking technique consist of?
The Corneal Cross-Linking technique consists of instilling a Riboflavin eye drop on the cornea and then applying UVA radiation. This union, according to the specialists in Ophthalmology, causes a reaction that strengthens the corneal collagen and, in this way, the evolution of Keratoconus can be stopped.
Advantages of Corneal Cross-Linking
The Cross-Linking technique makes it possible to delay or avoid a corneal transplant by restoring corneal rigidity. It is an excellent therapeutic method with excellent results that can be performed alone in initial degrees of keratoconus, or in combination with intracorneal rings and/or phakic lenses in more advanced degrees.
The results of Corneal Cross-Linking are better than those obtained with corneal transplantation, the restoration of vision is much faster, and there is no risk of rejection.
The most advanced and effective technique at the moment is the Accelerated Transepithelial Cross-Linking with iontophoresis. As it does not remove the epithelium or most superficial layer of the cornea, postoperative discomfort is minimal, and as it is accelerated, the duration of the procedure is less than 15 minutes per eye.
As the Cross-Linking Corneal technique is a simple, non-invasive procedure that is performed in the operating room on an outpatient basis -without hospitalization-, it does not entail any risk.
Preparation of the patient for the Cross-Linking Corneal technique
Before undergoing the Cross-Linking Corneal technique, the patient must perform an adequate palpebral hygiene and apply an antibiotic eye drop 3 days before the treatment. In addition, you must fast for 6 hours prior to the procedure.
What follow-up is required for the Corneal Cross-Linking technique?
After undergoing the Corneal Cross-Linking technique, the patient must wear a therapeutic contact lens for the first 48-72 hours. In addition, the patient must also be treated with an oral anti-inflammatory and cycloplegic eye drops to avoid any pain or discomfort. During this time, due to pupil dilation, blurred vision will be normal.
Then, for 20 days, the patient should apply antibiotic and anti-inflammatory eye drops, as well as artificial tears for 3 months. In addition, make-up and non-sterile water should be avoided for the first 15 days.
